Any browser I've ever used (standard ones, that is, not the oddballs like AOL's browser) allow you to selectively delete cookies. They also allow you to select what part of the history you want to delete, such as stored passwords. I don't delete those, just all the rest. As far as it being a pain, sure, it can be. However, bear in mind that all cookie strings are subject to corruption over time. That being the case, one would want to do this routinely to begin with, to prevent the strings from getting too long due to repeat site visits.
